Shares in India's Tata Communications Ltd gain as much as 2.2 percent after analysts cite the company executives as saying that although October-December revenue would be impacted by seasonal weakness, it was broadly in line with seasonal trends.

Tata Consultancy Services is also positive about the demand environment, according to analysts who attended a briefing by executives including the software service exporter's Chief Financial Officer Rajesh Gopinathan.

"Tata Consultancy Servicesremains confident of a solid demand environment. We believe TCS can sustain the gap in revenue growth and margins versus the industry," said Kotak Institutional Equities in a report on Tuesday.
